The militants belong to the Borok National Council of Tripura (BNCT), a sister organisation of the banned National Liberation Front of Tripura (NLFT).

They also deposited a large cache of arms and ammunition, including AK series rifles, three mortars and foreign made revolvers.

Militants belonging to various rebel groups in the northeast have set up about 100 camps and hideouts in different parts of Bangladesh, specially Sylhet district and Chittagong Hill Tracts (CHT) in the mainly hilly region of Bangladesh bordering India’s Tripura, Mizoram and Meghalaya states.

“We have managed to escape from our camps in CHT after Bangladesh launched anti-insurgency operations in different parts of that country,” Reang told reporters.

With this, about 160 tribal guerrillas of NLFT and All Tripura Tiger Force (ATTF), including some dreaded ultras carrying rewards of Rs.250,000 each and having Interpol arrest warrants, have fled from their Bangladeshi camps and surrendered to Indian security forces.
